.said chainengages ,said rollers `-as the ber 8 are brackets 10 Which support the rollers 11, so that the chain 5 contacts With the rollers whereby the latter hold the trolleys and chain directly in line With their supporting rail 3.

It willbe ,presumed that the conveyer completesfacircle inside the room, whereinl the opening 2 is formed and is then returned to the same level as the opening 1 and in so doingfiti is returned inznth-e convention al l man: ner in order: thata. comparison.` may. be had. between the conventional type of conveyer and the present novel form. In tlie-conventional form the continuation oftherail 3 is indicated by the numeral" 3"' having the together by a chain, and rollers mounted upon the other of said rails for engaging said chain.

t. A trolley conveyer comprising a pair of spaced rails bent to form a helix, trolleys mounted on one of said rails and connected together by a chain, removable brackets mounted upon the other of said rails, and rollers supported b-y said brackets in a positioirvvhereby.'theyengagesaid cha-in as the trolleys movealongthe tirstpnamed rail.

5. A trolley conveyor comprising a pair of spaced' rails bent to form a helix, trolleys mounted on one of said rails, a chain connecting said" trolleys together and adapted to propel said trolleys along said rail7 and means supported by the other of said rails for guiding said chain.
